Description
An anemometer measures wind speed. The “DINES PATENT PORTABLE ANEMOMETER 84” inscription on this example refers to William Henry Dines (1855-1927), the English meteorologist who described a metal pressure tube anemometer of this sort in 1892. The “L. CASELLA, LONDON” inscription is that of Louis Paschal Casella, an Italian instrument maker who opened a shop in London in 1848, and offered a wide range of meteorological, mathematical, optical, and philosophical instruments, and photographic apparatus. The firm became C.F. Casella in 1897, and C. F. Casella & Company Ltd. in 1910.
